OpenEdge Development:<br />Progress 4GL Reference / Division operator

Release 10.1A: OpenEdge Development:
Progress 4GL Reference

/ Division operator

Divides one numeric expression by another numeric expression, producing a decimal result.

Syntax
expression / expression 
expression
An expression that evaluates to a numeric value.
Example

This procedure divides the number of items allocated by the number of items on hand, producing a decimal value. The multiplication operator (*) converts that decimal value to a percentage.
r-div.p
DISPLAY "INVENTORY COMMITMENTS AS A PERCENT OF UNITS ON HAND".

FOR EACH item:
  DISPLAY item.item-num item-name alloc on-hand (alloc / on-hand) * 100
    FORMAT ">>9" LABEL "PCT".
END. 
Notes

Progress always performs division as a decimal operation (the product of 5 / 2 is 2.5, not 2). If you assign the result to an integer field, Progress rounds the decimal to make the assignment. When you want Progress to truncate a quotient to an integer, use the TRUNCATE function (TRUNCATE(5 / 2, 0) is 2).

The result of dividing a number by 0 is the Unknown value (?), and Progress does not display an error message.
